Python fallback code unreachable due to commented preprocessor directive

The #else preprocessor directive was changed to //#else (a comment) at multiple locations, breaking the conditional compilation structure. The reflection-based fallback code that dynamically loads Python.NET at runtime is now unreachable when PYTHONNET_AVAILABLE is not defined. When the symbol is not defined, only return false; executes (or nothing for the third location), completely skipping the fallback path that was intended to detect Python.NET at runtime. This silently breaks Python interop for users without compile-time Python.NET support.

Silent null return when holon cast fails after search

The search pattern was changed from SearchHolonsForParentAsync<IOmiverse> to SearchHolonsForParentAsync<Holon> with a subsequent as IOmiverse cast. When the search succeeds but the as cast fails (returning null), the method returns without setting an error, leaving result.Result as null. Callers receive a success result with null data, which could cause null reference exceptions or silent failures downstream. The same pattern appears in GetOrCreateUserMultiverseAsync, GetMagicVerseAsync, and GetGrandSimulationAsync.

Race condition in lazy-initialized provider properties returns null

The newly uncommented provider properties (EOSIO, Ethereum, Telos, ActivityPub) use Task.Run to asynchronously initialize the backing field but immediately return the field value without awaiting completion. On first access, this returns null because the async registration hasn't finished yet. The fire-and-forget pattern means callers receive null and subsequent accesses may still race with the ongoing initialization.

Python docstring regex matches wrong quote count

The regex pattern for extracting Python docstrings uses """""""""" (10 quote characters) in a C# verbatim string, which translates to 5 actual " characters in the pattern. However, Python docstrings use triple quotes ("""). The pattern will never match standard Python triple-double-quote docstrings, causing ExtractPythonDocstring to always return empty for """-style docstrings.

Provider registration silently fails with null result

The NEAROASIS and MoralisOASIS switch cases have their implementations commented out but still exist in the switch statement. When either provider type is requested, the case executes and breaks without setting result.Result or result.IsError. The caller receives a result with IsError=false (success) but Result=null (no provider), causing a silent failure. This can lead to null reference exceptions downstream when code assumes a successful result contains a valid provider.

Duplicate PHP enum values are not true aliases

The Php and PHP enum values are documented as aliases but in C# enums, separate values automatically receive different underlying integers. Comparing InteropProviderType.Php with InteropProviderType.PHP will return false since they're distinct values. For true aliasing, both values would need to be explicitly assigned the same integer value (e.g., PHP = Php).

Filtered display causes wrong metadata entries to be edited

The ManageMetaData method displays metadata entries with numbered indices while filtering out hidden keys ("WEB5STARNFTId" and "{{{newnft}}}"). However, when the user selects an entry to edit or remove, the code uses metaData.Keys.ElementAt(index - 1) on the unfiltered dictionary. This mismatch causes users to edit/remove the wrong entry, or accidentally modify hidden internal keys. The index validation also uses unfiltered metaData.Count, allowing selection of indices that don't correspond to visible items.

Empty ChainId string causes FormatException during provider initialization

The BigInteger.Parse calls for AvalancheOASIS and BaseOASIS will throw a FormatException if ChainId is configured as an empty string. The null-coalescing operator ?? only handles null, not empty strings. If a user sets ChainId = "" in configuration, BigInteger.Parse("") crashes the provider initialization. Similarly, a value of "0x" (hex prefix with no digits) would cause Substring(2) to return an empty string, also throwing. Missing validation for empty or malformed ChainId values before parsing.

Factory method missing cases for new interop provider types

The CreateProvider switch expression only handles 9 of the 24 InteropProviderType enum values. The new enum values added in this commit (TypeScript, Ruby, Php, PHP, Lua, Perl, Kotlin, Scala, Groovy, Clojure, Dart, R, Julia, ShellScript, PowerShell) are not handled, causing NotSupportedException even though their corresponding provider classes exist and are registered in CreateDefaultManagerAsync. Calling CreateProvider(InteropProviderType.PHP) will fail despite PhpInteropProvider being available.

Hardcoded API key exposed in source code

High Severity

A CoinGecko API key (CG-zG3a2tbc6QybLVKcknucz1Hz) is hardcoded directly in the source code URL string. This exposes the credential in version control, making it accessible to anyone with repository access and potentially compromising the key. The class comment on line 12 states "no API key required" which contradicts the implementation. API keys belong in configuration files, environment variables, or a secrets management system.

Null reference when accessing error message after null check

Medium Severity

The condition !(saveWalletsResult != null && saveWalletsResult.Result != null && !saveWalletsResult.IsError) explicitly handles saveWalletsResult being null, but when it is null, the condition evaluates to true (entering the error block), and then saveWalletsResult.Message is accessed, throwing a NullReferenceException. The null check in the condition contradicts the assumption in the error handler that saveWalletsResult is non-null.
